A set of methods that helps a home manager object communicate changes to its delegate.
- iOS 8.0+
- tvOS 10.0+
- watchOS 2.0+
Implement this protocol and set your object as the delegate of a
HMHome object if you want to track changes to a collection of homes.
HomeKit invokes delegate methods to notify your app of changes to the state of the home network. In general, if your app invokes a HomeKit method with a completion handler parameter and the method is successful, the associated delegate message is sent to other HomeKit apps running on the same or remote iOS devices. If your app initiates the change, the delegate message is not sent to your app, so you should add code to both the completion handler and the associated delegate method to reload data and update views as needed.
